WATER-GAGE.

Specification of Letters Patent.

Patented a as, rare.

Application filed May 18, 1914. Serial No. 839,405.

To all whom it may concern:

Be it known that I, Nonnomvn L. VIL- LinMs, a citizen of the UnitedStates, residing at Sayre, in the county of Beckham and State ofOklahoma, have invented certain new and useful Improvements in VVater-Gages, of which the following is a specification, reference beinghad tothe accompanying drawings.

This invention relates to new and useful improvements in water gages andmore particularly to a water gage adapted for use upon steam boilers andthe like, thennain object of the present invention being the provisionof a water gage adapted to be applied to the front end of a boilerandpreferably adapted to be used upon locomotive boilers, theconstruction being suclr that the water contained within the gage willbe visible to both the engineer and the the man.

Another object of the present invention is the provision of a water gageof the above character which will possess advantages in points ofeliieiency and durability, is inexpensive to manufacture and, at thesame time, is simple in construction and operation.

lVith the above and other objects in view, the invention consists in thenovePfeatures of construction, combination and arrangement of parts aswill be hereinafter referred to and more particularly pointed out in thespecification and claims.

In the accompanying drawing forming a part of this application, Figure 1is an elevation of a water gage constructed in accordance with myinvention. Fig; 2 is a transverse sectional view taken on the line 2-2,Fig. 1; and Fig. 3 is an enlarged sectional view taken on the line 3+3,Fig. 2. Fig. 4: is a detail view of'the gaskets 27.

Referring more particularly to'the drawing, 1 indicates the body of awater gage which is preferably triangular in cross section and formedofmetal or other suitable material. The side walls of the body 1 areprovided with spaced openings 2 andextending inwardly upon the innerside of the body, around each opening, is a flange 3, having an annularflange 1 formed upon its inner end to form. a seat for a fiber gasket 5.Arranged within the openings 2 and bearing upon the gasket 5, is a glass6, whereby to close the openlngs 2 so that the water within the gagewill be plainly V1s1- ble from the outside. Extending outwardly from theouter wall of the body 1, is a flange 7 which is preferably annular inform and arranged within the flange is a rubber gasket 8 which isadapted to bear against the glassG to retain the same in position. v

The rubber gasket 8 is securely held in position by means of a'skeletonnut 9 which is removably mounted within the flange 7 and adapted to bearagainst the gasket to hold the same and the glass 6 in position. Itwill" be understood that the inner face of the-flange 7 and the outerface of the gasket 8 is preferably screw threaded so that they may bequickly and readily engaged or disengaged. It will be noted that byhaving the glass members 6 arranged between the gaskets!) and 8, it willbring the sam'e'dnto longitudinal alinement with the wall of thebody'ofthe gage and by having the flange 7 extending outwardly from the wallyitwill provide a protecting ring for the glass, sotha-t the same will notbe readily broken by objects striking against the outer side of thegage. The ends of the body 1 are provided with central openings 10 and10 and mounted at the upper end of the'body of the water gage andconnecting with the opening 10 is a steam valve casing llhaving awvalveseat 12 and a movable valve 18, said valve having a stem14c whichextends upwardly through the upper end of the valve and is held in placeby means of: a removable cap 15, said valve stem hav ing a hand wheel 16formed upon its upper end, whereby the valve 18 may be readily seated orunseated, it being understood that the valve or stem 14 is adjustablymounted withinthe central portion of the cap 15.

Arranged within the opening 10, at the upper end of the body-1, is acollar 17, the lower end of'which is provided with screw threads,whereby'it may be readily engaged with the threads of the opening 10,said collar being" provided at its upper end with an out-turned flangeQOadaptedto be disposed withinthe sleeve 18 and engaged with theinturned flange 19 formed upon the loweredge' of the sleeve 18. Theupper end of the" sleeve 18 is provided with screw threads adapted to beremovably connected. witli'the lower end'of the valve 11, whereby toprovide for a direct communication between the body 1 and the valve 11.Connected with the lower end of the body 1, is

a water valve 21 which is provided with a end adapted to be seated uponthe valve seat 24. The lower end of the body 1, is formed substantiallytubular and extends into the upper end of the valve member 21. The upperend of the valve 21 is provided with a concaved seat 25 and threaded onthe upper end of the valve is a sleeve 26 which is mounted upon thelower tubular end of the body 1. The interior of the sleeve 26 at itsupper end is formed with a concave face complemental to the concave faceof the upperend of the valve casing 21. Disposed within the sleeve ormember 26 are the packing members 27, there being two pairs of thesemembers, each of the members being semi-circular in form. These membersare each approximately triangular in cross section, the outer faces ofthe members being convex so that when the valve casing is screwed intothe sleeve 26 the packing members will conform to the curvature of theupper end of the sleeve and the upper end of the valve casing and willform a water tight joint. This construction permits the gage glass to bereadily swung outward atits upper end when the union 18 is disengagedfrom the valve casing 11 and the union 26 is disengaged from the valvecasing21. In other Words, the construction described provides apackeduniversal joint between the lower end of the tubular stem 10 and valvecasing 21 which permits of an oscillation of the gage glass so that itmay be readily removed.

From the above it will be apparent that the valves 13 and 21 arenormally arranged in an open position, so that when the boiler isfilled, the gage willregister the amount of water contained within theboiler. It will be apparent that by forming the body 1 of metal andproviding the same with openings having transparent material arrangedthereover, it will eliminate the danger of breaking the Water gage andby forming the .body substantially triangular in shape, it

will be apparent that the same may be readily Visible fromdiiferentpoints. Arranged at the lower end of thevalve member 21, isadrain valve 28, whereby the body 1 may be readily drained of itscontents when desired. It is generally necessary to drain the body quiteoften to prevent settlings collecting therein and stopping up the valvemembers. It will be apparent that -my improved water gage may be quicklyand readily applied to any well known form of steam boiler and is soconstructed and arranged that it may be visible from various points. Itwill also be apparent that the same is extremely simple in constructionand can be manufactured and placed upon the market at a comparativelylow cost.

While I have shown and described the preferred form of my invention, itwill be obvious that various changes in the details of construction andin the proportions may be resorted to for successfully carrying myinvention into practice, without sacrificing any of the novel featuresor departing from the scope of the invention as defined by the appendedclaims.

Having thus described this invention, what I claim is 1. A device of theclass described includmg a hollow body, having a tubular steinprojecting from one end, a cap nut secured to said stem and interiorlyscrew threaded, a valve body having exterior screw threads engaging insaid cap nut and having an opening into which said stein passes, and twopairs of semi-circular packing rings, each pair being arranged tosurround the stem, said packing rings being each approximatelytriangular in cross section, the fiat faces of the packing rings bearingagainst each other, the inclined outer faces of the packing ringsbearing against the upper faces of the cap nut and against a seat formedin the valve body surrounding the central opening.

2. In a water gage, a hollow metallic many sided body each side wall ofwhich has a plurality of spaced openings, each opening being defined byanintegral wall extending out beyond the plane of the face of the bodyand inwardly extending into the body, said walls being spaced from eachother and the inwardly extending wall ha ving a seating flange at itsinner end, a gasket disposed within each wall against the seatingflange, a transparent disk arranged within the Wall and bearing againstthe gasket, a gasket disposed upon the outer face of each of said disks,'and a removable locking ring having screw-threaded engagement with theouter end of each wall and bearing against said gasket to removablyretain the disk in position whereby to permit the independent removal ofany one of said disks and its replacement.

In testimony whereof I hereunto aiiix my signature in the presence oftwo witnesses.
